ADOLPH B. DE MOURE, 9F PIPER CITY, ILLINOIS.

GRAIN-ELEVATOR.

To all whom it may concern:

Be it known that I, AooLrrr B. DE MoURE, a citizen'of the United States,residing at Piper City, in the county of Ford and State of Illinois,have invented certain new and useful Improvements in Grain-Elevators, ofwhich the following is a specification.

This invention relates to certain new and useful improvements in grainelevators.

One aim of the invention is to provide in an elevator ofthe classmentioned including pivotally connected sections, means for adjustingthe sections relatively angularly, and foradjusting the sectionsupwardly and downwardly and forward and rearwardly so that theymay becaused to assume any desired position for use.

A still further object of the invention is to provide an elevator whichmay be folded to compact form. V

Astill further object of the invention is to provide an elevator which'is so constructed that the endless conveyer traveling uponthe foldablesections of the elevator will not be disarranged when the sections areadjusted to different relative positions, or when they are folded.

lVith these and other objects in view, the invention consists in thenovel features of construction, combination and arrangement of parts,hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification: Figure 1 is a sideelevation of my improvedelevator. Fig. 2 is a longitudinal verticalsectional view through the same. Fig. 3 is a top plan view. Fig. 4 is atransverse vertical sectional view. Fig. 5 is a side elevation of theelevator folded. Fig. 6 is a detail perspective view of the upper end ofone of the standards and a portion of the ivoted brace therefor.

In the drawmgs, A indicates a pair of supportingmembers, which may bearranged upon a. car "or at any point desired where the elevator is tobe used. Arranged uponthe supports A.is a frame formed of parallel sidebars B connected together at one end by a cross beam 13. The forwardsupport A is 'of a greater length than the rear support, and securedupon the forward support is a pair of straps C having upturned ends C, Cthe upturned end C of each strap being extended upwardly beside thecorresponding side bar of the frame. A U-shaped strap D is arranged uponthe forward support A be- Specification of Letters Patent. Applicationfiled March 22, 1911.

are connected to the upturned ends C of the respective straps C- bypivot pins F in order to allow the braces to swing with the standardsand be folded when desired.

Pivotally connected to the upper end of each of the standards E arestraps G carried at the upper ends of braces G which are provided attheir lower ends with apertures adapted to register with openings formedin the side bars B. A bolt Gr is removably fitted through the saidregistering openings and serves to hold the braces in fixed position. Atthis point it will be understood that after removal of the bolt G thebraces maybeswung upwardly, and over to the other side of the fixedbraces F of the standards which will allow the standards to be foldedupon the side bars of the frame, as clearly shown in Fig. 5.

Arranged between the standards is the elevator proper consistingessentially of two trough-shaped sections I and J, the sides of whichhave rounded abutting ends. The sides of each section carry straps Kwhich are connected together by links K, in order to form a compoundhinge, so as to allow the sections to be folded upon themselves as shownin Fig. 5 or adjusted angularly-with respect to each other, in order toassume the desired position for use. Partitions I, J constitute thebottoms of the sections I and J respectively and it is over thesebottoms that the material being handled is carried by an endlessconveyer consisting of spaced chains L connected together by bars 1. Thechains L pass over sprockets-at the ends of drums M and N mounted forrotations at the outer ends of the sections I and J respectively. Bythis construction the endless conveyer is so mounted as to have itsupper stretch travel over the artitions I and J 'in such a manner as toelevate grain deposited upon the partitions of the lower section. The

grain is. discharged through a suitable discharge spout J provided atthe upper end of the section J. As a means for imparting movement to theendless conveyer, I provide the drum M with a shaft M having a universaljoint M to which is connected an extensible drive shaft M Fixed upon theupper ends of the standards E are frames 0 carrying pulleys O, 0 0 overwhich pass the cables which support the elevator sections and by meansof which the said sections are adjusted to assume various relativepositions, as will be later described. A pair of the cables indicated bythe letter P pass over the pulleys O, and each has one of its endsconnected to a cross-bar J upon the section J, and its other end woundaround one of a pair of winding drums R mounted upon a shaft R, mountedwith the side bars B. The shaft R carries ratchet wheels R adapted to beengaged by pivoted 'pawls R for locking the shaft against backwardrotation, and it will be seen that by rotating this shaft, the section Jcan be raised and lowered as desired and adjusted angularly with respectto the section I. Cables Q pass over the -pulleys O? and each has one ofits ends wound upon winding drums P carried by a shaft S. The other endsof the cables Q are connected to the upper end of the section I, and itwill be understood that by rotating the shaft S in one direction or theother, both sections may be bodily raised or lowered as desired.

Mounted between the sidebars B is a guide roller T upon which the innersection I rests and slides while being moved. In order that the elevatorsections may be moved forwardly and rearwardly between the standards, Imount within the frame a shaft U having a drum U upon which are wound inopposite directions cables V and W, the cable W being connected to acrossbar I adjacent the upper end of the section I and the cable V to across-bar I adjacent the lower end of the section I, whereby by operatinthe crank shaft U, one cable will be woun upon the drum U, and the otherunwound, in order to move the elevator vi'p either direction. It will beunderstood that the pulleys O serve to prevent disengagement of thecables from the pulleys when the standards 3 are swung upon theirpivotal supports. a

I claim-- 1. In an elevator of the class described, spaced uprights,plates secured to the opposite sides of each of the uprights andprojecting above the upper end thereof, spaced pulleys journaled betweeneach pair of plates, a bracket secured upon one plate of each pair, apulley journaled in the bracket, a conveyer comprising connectedsections, a windlng drum, cables connected to one of l the conveyersections and trained over the last mentioned pulleys and wound aboutsaid drum, asecond winding drum, and cables wound thereon and trainedover correspond ing ones of the first mentioned pulleys and connected tothe other section of the conveyer.

. 2. A conveyer comprising sections each including sides and a bottom,bars secured to the sides of eachsection at the meeting ends of thesections, a link pivoted to and extend. ing between the ends of the barsat each side of the conveyer, conveyer shafts mounted at the remote endsof the sections, a partition extending between the sides of each sectionabove the bottom thereof, and an endless conveyer apron trained over theshafts and having its lower-stretch traveling over the bottom of thesections and the upper stretch over the partitions thereof.

3. In an elevator of the class described, conveyer sections relativelyan'gularly adj ustable, connection between the sections comprising barssecured to the sides of the sections, the bars of one section eachhaving an end located near the bottom of the section and the bars uponthe other section each havin r an end located substantially at the topof the section, links extending between the said ends of thecorresponding bars, and

pivotally connected to the same, and means.

for relatively angularly adjusting the sections, the first mentionedsection beinv foldable to lie in inverted position upon t e secondmentioned section.

4. In an elevator of the class described, a

base, spaced uprights upon the base and foldably mountedthereon,conveyer sections supported between the uprights and relativelyangularly adjustable, connection between the adjacent ends ofthesections comprising bars secured to the sides of the sections, the barsupon one section each having tioned section being foldable upon saidlinks to lie in inverted position upon the secondmentioned section.

In testimony whereof I affix my signature in presence of two witnesses.
